Description

この考案は試験管などの攪拌混合に用いる試験管攪拌装置のヘッドにおいて、手持ち押当て攪拌と架装攪拌の双方を同時に使用可能とし、加えて架装容器をそのまま簡易遠心に使用可能とする円形ヘッドに関するものである。   This device is a test tube agitator head used for agitation and mixing of test tubes, etc., so that both hand-held pushing agitation and body agitation can be used simultaneously, and in addition, the body vessel can be used for simple centrifugation as it is. It relates to the head.

従来、この種の攪拌装置は、容器に攪拌力を伝達する部位であるヘッドを大別して手持ち押当て攪拌用と容器架装攪拌用の2種にて形成している。
さらに、攪拌の後工程として頻繁に行われる容器のスピンダウン操作においては、容器をスピンダウン用の遠心機に載せかえる必要があるが、この遠心機の容器架装部であるローターに、ある程度架装攪拌に必要な固定力を持たせる試みがあるものの、ローターは金属,合成紙樹脂製によって手持ち攪拌用の容器押当て部はなく、あくまで遠心機のローターの側からの攪拌用途へのアプローチであり、そのためここで主要にしている攪拌操作を充分に満足させ得るものではなかった。
なし
Conventionally, this type of agitation device is roughly divided into a head that is a part that transmits the agitation force to the container, and is formed by two types: a hand-held pressing agitation and a container frame agitation.
Furthermore, in the container spin-down operation that is frequently performed as a post-stirring process, it is necessary to replace the container with a spin-down centrifuge. Although there is an attempt to give the fixing force necessary for mixing and stirring, the rotor is made of metal and synthetic paper resin, and there is no container holding part for hand-held stirring, but it is only an approach to the stirring application from the centrifuge rotor side For this reason, the stirring operation mainly used here cannot be sufficiently satisfied.
None

このようにして円形ヘッドが2種に分かれていると、手持ち押当てと架装攪拌を同時使用するなどによる試料に適した攪拌が行えないという課題がある。しかも手持ち攪拌では押当て試験管などがヘッドとの間で滑って攪拌効率が上がらないという課題があった。   When the circular head is divided into two types in this way, there is a problem that stirring suitable for a sample cannot be performed by simultaneously using hand-held pressing and body stirring. Moreover, in the case of hand-held stirring, there is a problem that the pressing test tube slides between the head and the stirring efficiency does not increase.

本考案は、攪拌機本体との重量バランスを考慮して(ヘッドが大きいと、攪拌機本体が安定しない弊害が生ずる)大きさ厚さを検討して「手持ち押当て攪拌」と「架装攪拌」の双方を一台にて行えるようにするとともに、手持ち押当て攪拌の際は滑らずに効率よく攪拌し得るようにし、また架装攪拌ではユーザーの求めに応じてマイクロチューブを最低でも6〜8本以上は同時に架装し得るようにして1機種にて手持ち押当て攪拌と架装による攪拌が同時に行えるようにして、かかる課題を解決するようにしたのである。
また、架装攪拌の場合はそのまま回転させて遠心によるスピンダウンが行えるようにしたのである。
The present invention considers the weight balance with the agitator body (when the head is large, the agitator body is not stable), and the size and thickness are examined. In addition to being able to perform both in one unit, it is possible to efficiently stir without slipping during hand-held pushing agitation, and for body agitation a minimum of 6-8 microtubes according to user requirements As described above, this problem can be solved by allowing the hand-held pressing stirring and the stirring by the body to be performed simultaneously in one model so that the body can be mounted at the same time.
In addition, in the case of body stirring, it is rotated as it is so that it can be spun down by centrifugation.

本考案の円形ヘッドは、中央にすり鉢形に凹み、且つ凹凸周壁を多設した手持ち押当て攪拌用の円形凹部を設けたので、試験管,遠沈管等の先端がよく馴んで滑らずに能率よく手持ち押当て攪拌を行うことができるという効果を生ずる。またチューブチャックを多数設けたので、マイクロチューブ等の架装数を増大するニーズに応えることができるという効果を生ずる。   The circular head of the present invention has a concave shape in the shape of a mortar at the center and a circular concave portion for hand-held pushing and stirring with multiple concave and convex peripheral walls. The effect of being able to perform hand-held pushing and stirring well is produced. In addition, since a large number of tube chucks are provided, there is an effect that it is possible to meet the needs for increasing the number of mountings such as microtubes.

さらに架装攪拌の保持力を有すチューブチャックはそのままマイクロチューブを簡易遠心作用によりスピンダウンができるという効果を生ずる。   Furthermore, the tube chuck having the holding power for the stirrer stirrer produces the effect that the microtube can be spun down by a simple centrifugal action.

本考案は、試験管などの攪拌混合装置のヘッドにおいて、中央にすり鉢状に凹且つ凹凸周壁を多設した手持ち押当て攪拌用の円形凹部を設け、該凹部の外側に大小径のマイクロチューブ等を多数架装し得るチューブチャックを周設して、試験管,マイクロチューブなどに注入した試料を手持ち押当て攪拌と同時に架装攪拌ができるようにし、加えて架装容器をそのまま簡易遠心に使用可能にしたのである。チューブチャックは架装したマイクロチューブなどが振動攪拌によって抜け外れないように保持力を高めて構成する。   The present invention provides a head of a stirring and mixing device such as a test tube provided with a circular concave portion for stirring by hand holding with a concave shape in a mortar shape and a large number of concave and convex peripheral walls, and a large and small diameter microtube or the like outside the concave portion. A tube chuck that can mount a large number of tubes can be placed around, so that the sample injected into a test tube, microtube, etc. can be hand-held, pressed and agitated simultaneously. Made it possible. The tube chuck is constructed by increasing the holding force so that the mounted microtube or the like does not come off due to vibration agitation.

図1乃至図3は第1実施例の円形ヘッド3を示すもので、機体1の上部作動軸2に水平嵌着し、該円形ヘッド3は摩擦力のあるゴム板にて形成し、上下段の輪形板部6a,6bのそれぞれに4個づつにてチューブチャック13a,13bを設け、中央にすべり止め用の多重リング形の凹凸周壁14を有すタッチミキシング用の円形凹部15と、上段のチューブチャック13a間の三角壁面16にすべり止め突条列17を設けてなる。機体1のスイッチ10を操作して円形ヘッド3を振動させておいて、遠沈管12,マイクロチューブ8などをヘッド3の円形凹部15または三角壁面16のすべり止め突条17に先端を押し当てると、滑ることなくして効率よくタッチミキシングすることができることとなる。円形凹部14はすり鉢状に凹んでいるので図3(a)に示すように遠沈管12,マイクロチューブ8,試験管18などの先端を隙間なく押当てることができ、またマイクロチューブ8等は図3(b)に示すように側方の三角壁面16に設けた突条列17に先端を押し当てることですべりを防止して効率よくタッチミキシングすることができる。   1 to 3 show a circular head 3 of the first embodiment, which is horizontally fitted on the upper operating shaft 2 of the machine body 1 and is formed of a rubber plate having a frictional force. Tube chucks 13a and 13b are provided in each of four ring-shaped plate portions 6a and 6b, and a circular recess 15 for touch mixing having a multi-ring-shaped uneven peripheral wall 14 for preventing slipping in the center, and an upper stage Non-slip protrusion rows 17 are provided on the triangular wall surface 16 between the tube chucks 13a. When the circular head 3 is vibrated by operating the switch 10 of the airframe 1 and the tip is pressed against the circular recess 15 of the head 3 or the anti-slip ridge 17 of the triangular wall surface 16. Thus, touch mixing can be performed efficiently without slipping. Since the circular recess 14 is recessed in a mortar shape, the tips of the centrifuge tube 12, the microtube 8, the test tube 18 and the like can be pressed without gaps as shown in FIG. 3 (a). As shown in FIG. 3 (b), the tip can be pressed against the ridge row 17 provided on the side triangular wall surface 16 to prevent slipping and to efficiently perform touch mixing.

また架装攪拌するときは最大8本において架装したマイクロチューブ8を同時に振動させて内部の試料を攪拌混合することとなる。架装攪拌中の円形ヘッド3に手持ちの遠沈管12等を押し当てることで同時にタッチミキシングを行うこともできる。   In addition, when agitation is carried out, a maximum of 8 microtubes 8 are simultaneously vibrated to agitate and mix the sample inside. Touch mixing can be performed at the same time by pressing the hand-held centrifuge tube 12 or the like against the circular head 3 during the body stirring.

チューブチャック13a,13bは弾力を持って各マイクロチューブ8などを架装保持するので振動攪拌によってマイクロチューブ8などが抜け外れることは全く生じないものである。しかして、架装したマイクロチューブ8などはそのまま円形ヘッド3を回転し遠心させることで、攪拌によって内壁に付着した試料のすべてを底部に集めるスピンダウン作用を起こさせることができる。
このようにして本考案の円形ヘッド3は手持ち押当て攪拌と、多数のマイクロチューブ8を架装した攪拌とおよびスピンダウンの作業を一台にて行うことができることとなる。
Since the tube chucks 13a and 13b hold and hold the microtubes 8 etc. with elasticity, the microtubes 8 etc. do not come off by vibration agitation at all. Thus, the mounted microtube 8 and the like can rotate the circular head 3 as it is and centrifuge, thereby causing a spin-down action to collect all the samples attached to the inner wall by stirring at the bottom.
In this way, the circular head 3 of the present invention can perform hand-held pressing stirring, stirring with a large number of microtubes 8 mounted, and spin-down operations in one unit.

図4乃至図8は第2実施例の円形ヘッド3を示すもので、上面にすべり止め用の小突子4を多数突設した可及的に大きいタッチミキシング用の円形平面部5を設け、その外側に上がり傾斜を付した上下2段の輪形板部6a,6bを設け、これらに外向きのチューブチャック7a,7bを設ける。各チューブチャックは外向きの出入口が狭く中はほぼ円形にふくらんでいる。しかしてチューブチャック7aは図6(a)に示すように上下2段に連設して1.5ml乃至2.0ml容量の太さのマイクロチューブ8を架装するようにしており、下段のチューブチャック7bは0.5mlの太さのマイクロチューブ8用を架装するものであり、架装すると図6(b)に示すように上段にて上端が押え止められるようになっている。いずれのチューブチャック7a,7bも架装したマイクロチューブ8が攪拌の振動によって抜け外れない強化構造になっている。実施例ではこれらのチューブチャック7a,7bを交互に8個づつ設けている。なお9はすべり止めのための突条列である。   4 to 8 show the circular head 3 of the second embodiment, in which a circular flat portion 5 for touch mixing, which is as large as possible, provided with a number of small protrusions 4 for preventing slipping is provided on the upper surface. Upper and lower two-stage annular plate portions 6a and 6b are provided on the outside and inclined, and outward tube chucks 7a and 7b are provided on these. Each tube chuck has a narrow outward opening and is swelled in a substantially circular shape. As shown in FIG. 6 (a), the tube chuck 7a is arranged in two upper and lower stages so as to mount a micro tube 8 having a thickness of 1.5 ml to 2.0 ml, and a lower tube. The chuck 7b is used to mount a microtube 8 having a thickness of 0.5 ml. When mounted, the upper end of the chuck 7b is held down in the upper stage as shown in FIG. 6 (b). Each of the tube chucks 7a and 7b has a reinforced structure in which the mounted microtube 8 is not detached by the vibration of stirring. In the embodiment, eight tube chucks 7a and 7b are alternately provided. Reference numeral 9 denotes a ridge row for preventing slipping.

機体1の前面のスイッチ10を操作し且つボリュームコントローラ11を廻して円形ヘッド3を作動させると、最大16本において架装したマイクロチューブ8を同時に攪拌することとなる。
円形平面部5に手持ちした試験管18の先端を押し当てることでタッチミキサーとして使用することができる。円形平面部5に設けたすべり止め用の小突子4により試験管18は滑ることなく効率よくタッチミキシングすることができることとなる。
When the switch 10 on the front surface of the machine body 1 is operated and the volume controller 11 is turned to operate the circular head 3, the microtubes 8 mounted at the maximum of 16 are simultaneously stirred.
It can be used as a touch mixer by pressing the tip of the test tube 18 held on the circular flat portion 5. The test tube 18 can be efficiently touch-mixed without slipping by the non-slip small protrusion 4 provided on the circular flat surface portion 5.

なお、架装したマイクロチューブ8の攪拌中に同時に手持ち試験管18等のタッチミキシングをすることができる。そして円形ヘッド3を回転作動にして架装しているマイクロチューブ8をそのままスピンダウン作業をさせ得る点も前例と同じである。   In addition, touch mixing of the hand-held test tube 18 or the like can be performed simultaneously with stirring of the mounted microtube 8. The microtube 8 mounted by rotating the circular head 3 can be spun down as it is, which is the same as the previous example.

本考案の円形ヘッドは以上のようにして、試験管等の手持ち押当て攪拌と架装攪拌を同時に行えて、且つそのまま回転による遠心作用によりスピンダウンもできることになり、しかもマイクロチューブの架装本数を増大し、且つすべりのないタッチミキシングを可能とする効率的で使い勝手のよい円形ヘッドとして広く利用できるものである。   As described above, the circular head of the present invention can simultaneously hold and agitate test tubes, etc., and stir the body, and can also be spun down by the centrifugal action of rotation as it is. In addition, it can be widely used as an efficient and easy-to-use circular head capable of increasing touch and non-slip touch mixing.
